Zhecheng County (Chinese: 柘城县; pinyin: Zhéchéng Xiàn) is a county under the administration of the prefecture-level city of Shangqiu, in the east of Henan province, People's Republic of China.
Zhecheng is a major center for producing lab diamonds in China. For years, the city's factories focused on producing diamonds for industrial applications, including diamond-tipped cutting tools, drill bits, and diamond-based grinding powders. Since the 2010s, diamond companies in Henan have pivoted to the higher-margin jewelry business. Once roughly processed, the stones are typically shipped to Surat, India where lower labor costs make polishing more economical.
